综合测试仪CMD55 指标：GSM测试 | |
产品信息： | CMD55产品特点： ·是测量GSM及GSM1800移动电话的紧缩式单元 ·通过RS232，IEC/IEEE远控 ·前面板有多功能连接器 ·话音编码器/解码器可被集成 ·可选择安培表和伏特表 ·高敏感度二级RF输入 ·可改进为GSM、GSM1800及GSM1900测试 Characteristics The CMD52 is a compact unit for testing GSM900 mobiles. The CMD55 is furthermore capable of testing GSM1800 (formerly named PCN orDCS1800) and GSM1900 (formerly named PCS or DCS1900) mobile phones. Both models are favourably priced and combine small dimensions with high measurement accuracy and speed. The testers range of capabilities includes all signalling generator and measurement functions required for verifying the correct operation of the DUT (Device Under Test). Thanks to its fast go/nogo tests and accurate analysis using optional extensions CMD52 and CMD55 are equally well suited for R&D production and high-end service and production. Based on the wide-range know-how of Rohde & Schwarz in digital radiocommunication testing which not least was obtained in developing type-approval test systems such as the GSM900 and GSM1800 system simulators both CMD models are top-grade testers for present and future measurement applications. Test capabilities To test mobile phones the CMD simulates a GSM900 1800 or 1900 |
